摘要： PROBLEM TO BE SOLVED: To provide a facility for producing a saturated raw material salt solution which comprises a compact dissolution tank and saves consumption of the raw material salt by obtaining the saturated salt solution with a prescribed concentration.
SOLUTION: In the case of dissolving a raw material salt 2 in supplied water 1, the supplied water is detoured around a barrage 3D formed in a raw material salt dissolution tank 3A for detouring supplied water 1 so as to increase the contact surface area of the supplied water 1 with the raw material salt 2 and obtain the saturated salt solution 4 with a high salt concentration.

摘要： PROBLEM TO BE SOLVED: To simplify the structure of a reinforcing part of a column and increase earthquake resistance by forming, on the column, a folded end main surface folded in the same direction as a folded end side surface and a reinforcing part which is formed, so that both side surfaces are folded in a direction perpendicular to the main surface and the folded end side surface is brought into contact with the folded end main surface. SOLUTION: An end side surface is folded in a direction perpendicular to a main surface 6 to form an upward folded end side surface 13, and an end principle surface is folded in the same direction as the folded end side surface 13 via a notch, to form an upward folded end main surface 14. Both side surfaces 7 are folded in a direction perpendicular to the main surface 6, and a reinforcing part 8 is formed in such a way that the folded end side surface 13 brought into contact with the folded end main surface 14 is integrally formed on the end part of a column 4. Since a U-shaped column 4 and the reinforcing part 8 can be formed integrally of a single flat plate through press working in the same process, the structure can be simplified and operating efficiency is improved. When a housing is vibrated in the depth direction and the width direction, mechanical strength is increased, and earthquake resistance is improved.

摘要： PROBLEM TO BE SOLVED: To ensure the safety of passengers and crew by detecting landslide, snowslide or the like to a railroad by means of an inexpensive device and stopping a train utilizing a track circuit and a signal facility. SOLUTION: Tension variation detectors 2A, 2C are installed at a side (one side or both sides) of a rail 1, wires 3A, 3B, 3C, 3D are attached to both sides and each one end is fixed to piles 4A, 4B, 4C, 4D through a spring in the tension-retaining state. The tension variation detector 2A (2C) does not perform detection the case where the tensions of the wires 3A, 3B (3C, 3D) of both ends are approximately equal and performs detection when difference of the tension becomes a set value or higher to close a contact at the inside. When the contact (at least one contact) of the tension variation detectors 2A, 2C is closed, left and right rails 1 are connected by electric wires 8A, 8C for rail short circuit and a power source circuit 5 of the existing track circuit 10 for train detection becomes in the short circuit state. Thereby, a relay 6 becomes in the non-application state and a signal 7 becomes red display. The relay 6 becomes blue display in the application state of the power source. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a diaphragm electrolytic device and a Ca/Mg removal method therefor which can lengthen the life span of an ion-exchange membrane and reduce the running cost of a drinking water treatment plant.
SOLUTION: In the Ca/Mg removal method for this device, dilution water 1A obtained by removing Ca/Mg contained in feed water 1 by a Ca/Mg removal machine 3 disposed on the supply side is fed to a dissolving tank and an electrolytic cell 4. Thereby the deposition of Ca/Mg on the ion-exchange membrane 9 is prevented to lengthen the life span of the ion-exchange membrane 9 and to reduce the running cost of the drinking water treatment plant.

摘要： PROBLEM TO BE SOLVED: To prevent generation of electrical shocks and simplify a clamping process of firmly joining parts to each other by forming a ground conductive path set, so that clamping hardware and a protrusion formed on a flat part pierce through the insulating film by the clamping force of the clamping hardwire and reach a metal plate. SOLUTION: The cut area of a spring washer 12 bursts through the printed film of a corresponding surface 5A and reaches the metal part thereof by the rotation of a bolt head 11A during clamping process. A protrusion 18 bursts through the painted film by clamping clamping hardware 13 and reaches the metal part of a corresponding surface 3A to form a ground conductive path. Since the charging current of a housing 1 flows in a sequence of a corresponding surface 5A, the spring washer 12, a bolt 11, the clamping hardware 13, a flat part 14, the protrusion 18, the corresponding surface 3A, and a ground, E the potential becomes zero at all times, so that there is no possibility of receiving electric shocks. Effective clamping operation can be obtained, and the corresponding surfaces 3A, 5A can be fastened firmly to each other.
